Description

Footbridges, bridges and slopes of the expandable}

The present invention is a technology related to the extended footbridge installed along the curb portion of the bridge or the road surface, more specifically, the main beam is installed with a plurality of support structures on the outer side of the concrete structure in the bridge or the surface, the upper part of the main beam A rubber pad is placed on the rubber pad to absorb shock, and an aluminum floor with ribs and wires is installed on the rubber pad, and concrete or elastic pavement is installed on the floor to form a footbridge. As it increases, structural stability is high, and concrete or elastic paving material is installed on aluminum flooring, which not only provides excellent adsorption and durability of footbridges, but also enhances stability, while the rubber pad absorbs shocks applied to the floor of footbridges for durability and stability. Of bridges and facades It is a description of long Indian footbridge.

In general, bridges are structures such as bridges that are constructed across rivers, lakes, straits, reservoirs, etc. to enable vehicles to travel. These bridges are composed of alternating bridges, bridges, and girders and tops installed across them. It consists of a structure.

Such bridges may be provided with sidewalks for the passage of vehicles as well as pedestrians, where sidewalks are pedestrians or pedestrians, which are not installed by a separate method when the bridge is installed. The edge of the road is secured by railings and used as sidewalks.

In other words, when the width of the roadway is relatively wide on the bridge, the separate walkways are partitioned and the roadway and sidewalks are installed strictly and safely. Otherwise, the roadway and sidewalks are installed together by installing railings at the edges of the roadway.

If the road and sidewalk are not separated from the existing bridge, if a person walks to the edge of the bridge, there is a problem that a safety accident occurs for both the vehicle and the pedestrian.The existing bridge is to be removed and rebuilt In this case, since the cost is enormous, a method of additionally installing sidewalks has recently been applied to existing bridges.

As a method for separately laying a sidewalk in a conventional bridge, Korean Patent Registration No. 10-1090400 has been presented. Looking at the above prior art, the support piles are placed on the ground at regular intervals along the sides where the slope of the road begins. Embedding vertically; Forming an extended bridge support block which is joined to a head of the support pile and protrudes a predetermined amount to the ground; And installing an extended footbridge having a predetermined road width in a cantilever form on the extended footbridge support block to enable delivery of a bicycle and sidewalks.

The prior art embeds a plurality of support piles in the ground, forms an extended footbridge support block on the head of the support pile, and installs an extended footbridge in the form of a cantilever beam on the extended footbridge support block. Therefore, there is a problem that the construction cost is excessively required.

In addition, as a method for separately laying the sidewalks in the conventional law surface and the retaining wall, Republic of Korea Patent No. 10-1122681 has been presented, looking at the above prior art, a plurality of bridge pedestal, a fixed type is installed on the bridge pedestal A bracket, a plurality of square-zinc angle tubes fixed on the bracket, a railing supporting square steel pipe installed on an upper portion of the mounting bracket, a pedestrian railing installed on a side of the railing supporting square steel pipe, and a plurality of squares It consists of a flooring material installed in the vertical direction on top of the zinc conduit.

The prior art has the advantages of relatively simple construction and installation structure, but when the pedestrian passes over the flooring material or the bicycle runs, the impact on the flooring material is not dispersed and absorbed to the outside, causing shaking and noise in the flooring material. As a result, there is a problem that does not provide a sense of stability for pedestrians.

Republic of Korea Patent No. 10-1090400. Republic of Korea Patent No. 10-1122681.

The present invention has a problem in that the construction process and installation structure is very complicated in the prior art of the extended footbridge, which is hypothesized on a conventional bridge or the front surface, excessive construction cost, and when a pedestrian passes over a floor or a bicycle runs, It is a technology devised to improve the problems that do not provide stability to pedestrians due to shaking and noise, and the main beams are installed with a plurality of supporting structures on the outer side of the concrete structure in the bridge or the surface, and absorbs the shock on the upper part of the main beam. While the rubber pad is laid, an aluminum floor with ribs and wires formed in a lattice form is installed on the rubber pad, and an object of the present invention is to provide an extended bridge of a bridge and a front surface, in which concrete or elastic packaging material is installed on the floor.

The present invention is to realize the desired purpose as described above,

A plurality of supporting structures fixed at regular intervals on the outer side of the concrete structure in the bridge and the front surface, and configured in a conical solid shape; A height adjuster installed at an outer end of the support structure; A main beam connected to the upper portion of the structure and the height adjustment opening; A footbridge installed at an upper portion of the main beam and having any one of concrete or elastic packing material installed therein to form a bottom surface; And a safety fence connected to the outer edge of the footbridge.

In addition, as an embodiment of the present invention, the support structure is configured in the form of a long, pointed conical cone, one end is a circular flange formed in a circular shape at a wide end, the fixing flange is a plurality of anchors on the outer side of the structure It is characterized by being fixed with a bolt.

In addition, as an embodiment of the present invention, the footbridge is installed on the upper portion of the main beam in a wide range corresponding to the main beam, and the holder and the flange portion is formed on both sides, respectively, the inside of the ribs and wires in the form of a grid; A rubber pad placed between the flooring material and the main beam; The floor surface is formed by installing any one of concrete or elastic packaging material on top of the flooring material.

According to the embodiment of the present invention, the structural stability is high because of the increase of the supporting fixing force with the distribution of load in the expanded footbridge, and the concrete or elastic packaging material is installed in the aluminum flooring material, as well as excellent adsorptivity and durability of the footbridge, The rubber pad absorbs the impact on the bottom of the footbridge while raising the planet, thereby increasing durability and stability of pedestrians.

In addition, in the embodiment of the present invention, when the pedestrian walks or rides the bicycle over the footbridge, the rubber pad absorbs the shock transmitted to the main beam from the floor where the concrete or the elastic packing material is installed, so the shaking and noise of the footbridge on the main beam are prevented. By preventing the above, there is an effect of increasing stability to pedestrians and further improving durability.
